Removal of boilers, the design, materials and component specification, installation, commissioning of GSHP systems at 3 sites within the Calderdale Council area, namely a:-
• Museum VGSHP –
• Hall HGSHP –
• Library VGSHP –
The Heat pumps at each site are heating optimized based on outdoor weather compensation. To enhance overall annual system efficiency and delivery at these sites, the heat pumps are arranged as 2-stage arrangement to produce higher water temperature, up to 65DegC in space heating, when outdoor air temperatures require. The 1st stage heat pumps feature multiple Stage-1 GSHP units, in cascade, which are connected to the ground loop and provide heating up to 50DegC to the Stage 1 buffer tank. Initially, the 1st Stage-1 heat pump will be called on. As demand increases, the Stage 1 slave unit(s) will be brought on to further compensate and, at this time, both compressors will be operating. As demand decreases, compressors stop, the slave heat pump is shed and the master heat pump will turn off based on reaching set point.
Key Activities and Achievements
Product Design
- Conducted a thorough site assessment to understand the existing heating system and requirements. Completed ground loop Designs for each site, P&ID, Revit Drawings and description of operations for each site.
- Collaborated with the council administration to plan the project timeline and minimize disruptions to the site’s operations.
Health and Safety
- Developed a comprehensive Health and Safety Plan, including risk assessments, method statements, and site-specific safety measures.
- Ensured all personnel involved in the project received appropriate health and safety training, including CSCS cards, asbestos awareness, and working at heights.
Coordination and Subcontractor Management
- Engaged qualified and experienced subcontractors for specialized tasks such as asbestos removal, electrical connections, and pipework.
- Conducted regular coordination meetings with subcontractors to ensure adherence to the project schedule and quality standards.
Works Execution
- Safely removed the old boilers and associated pipework, following proper disposal procedures for any identified asbestos-containing materials.
- Drilled and excavated ground to receive all ground arrays.
- Installed new energy-efficient heat pumps, connecting them to the existing heating system and ensuring proper functioning.
- Tested and commissioned the heat pumps, ensuring compliance with regulatory requirements and performance expectations of design.
Quality Control and Handover
- Conducted regular inspections and quality checks to monitor the progress and compliance with the project specifications.
- Prepared comprehensive handover documentation, including as-built drawings, operation manuals, and maintenance recommendations.
- Collaborated with the council staff to provide training on the operation and maintenance of the new heat pumps.
